Detailed Description

The following describes the embodiments of the present invention in further detail with reference to the accompanying drawings.

By figure 1 to figure 4 and give, axial injection tube 1 around including, the coaxial gliding syringe 2 around being equipped with in the injection tube 1, axial injection pipe 3 about 1 front side of injection tube is equipped with, 2 rear end faces of syringe are located injection pipe 3 rear, 3 upper end threaded connection of injection pipe have a medicine storage bottle 4, the nipple of injection tube 1 is connected with sheath 6 through water conservancy diversion hose 5, set up a plurality of leakage holes 7 along its circumferencial direction equipartition and with 6 inside intercommunications of sheath on the 6 outer fringe faces of sheath, be equipped with the check valve 8 of opening towards sheath 6 in the nipple of injection tube 1.

In order to facilitate the pushing head 2 to move back and forth, the rear end of the pushing head 2 is hinged with a push rod 9 in the front-back axial direction, a handle 10 in the up-down direction is arranged on the lower side of the injection tube 1, and the rear end of the push rod 9 extends out of the injection tube 1 and is hinged with the handle 10 through a swing rod 11.

In order to enable the swing rod 10 to be automatically reset, a left-right axial torsion spring 12 is arranged between the handle 10 and the swing rod 11.

In order to prevent the liquid medicine from flowing out when installing the medicine storage bottle 4, the medicine storage bottle 4 on the coaxial dead lever 13 that is equipped with on the lateral wall, coaxial sliding connection has shrouding 14 on the dead lever 13, the lower surface of shrouding 14 can with the contact of the lateral wall under the medicine storage bottle 4, the cover is equipped with on the dead lever 13 and is located shrouding 14 and the spring 15 between the lateral wall on the medicine storage bottle 4.

In order to make the liquid medicine in the medicine storage bottle 4 flow into injection tube 1 through

injection tube

3, 3 up end of injection tube can contact with 14 lower surfaces of shrouding, injection tube 3 upside seted up a plurality of flow guide holes 16 along its circumferencial direction equipartition and rather than inside intercommunication, air vent 17 that link up about the wall is seted up on medicine storage bottle 4, the dismantlement is connected with rubber buffer 18 in the air vent 17.

In order to avoid damaging the inner wall of the intestinal tract of the infant, the front end surface of the sheath 6 is a convex spherical surface.

When the utility model is used, the medicine storage bottle 4 filled with liquid medicine is rotated, so that the medicine storage bottle 4 is connected with the medicine injection pipe 3, when the upper end surface of the medicine injection pipe 3 is contacted with the lower surface of the closing plate 14, the medicine storage bottle 4 is continuously rotated, the medicine injection pipe 3 upwards pushes the closing plate 14 and extrudes the spring 15, the lower surface of the closing plate 14 is separated from the lower side wall of the medicine storage bottle 4, when the flow guide hole 16 is positioned inside the medicine storage bottle 4, the medicine storage bottle 4 is communicated with the inside of the medicine injection pipe 3 through the flow guide hole 16, and the liquid medicine in the medicine storage bottle 4 flows into the injection tube 1 through the medicine injection pipe 3 at the moment;

The sheath 6 is plugged into the anus of the infant, the rubber plug 18 is pulled out of the air vent 17, the handle 10 is held by hand, the swing rod 11 is pushed forwards, the swing rod 11 drives the pushing head 2 to slide forwards through the push rod 9, meanwhile, the torsion spring 12 deforms, the pushing head 2 moves forwards, the lower end of the medicine injection tube 3 is gradually shielded by the pushing head 2, the medicine liquid in the medicine storage bottle 4 cannot flow into the injection tube 1, the one-way valve 8 of the medicine liquid in the injection tube 1 is opened under the action of the pushing head 2 and flows into the sheath 6 through the flow guide hose 5, and the medicine liquid in the sheath 6 flows out through the liquid leakage hole 7 and enters the intestinal tract of the infant;

After the liquid medicine in the injection tube 1 is completely injected into the intestinal tract of the infant, the swing rod 11 is loosened, the upper end of the swing rod 11 swings backwards under the action of the torsion spring 12, meanwhile, the upper end of the swing rod 11 drives the pushing head 2 to slide backwards through the push rod 9, and when the pushing head 2 does not shield the lower end of the injection tube 3 any more, the liquid medicine in the medicine storage bottle 4 flows into the injection tube 1 through the injection tube 3 again;

Repeating the above operation for multiple times, injecting the liquid medicine in the medicine storage bottle 4 into the intestinal tract of the infant for multiple times in a small amount, and after the liquid medicine in the medicine storage bottle 4 is completely injected into the intestinal tract of the infant, pulling out the sheath 6 to complete the liquid medicine injection.
